not work for ck2 3.3.5.1

[mysoundmagic]

After completing the install_copy process and copying the DLCs to the CK2 folder, the DLCs are still not enabled. I have attempted this multiple times, including reinstalling CK2 from Steam.

Steam version: 1726256783
CK2 version: 3.3.5.1
OS: ubuntu 24.04

Note: CK2 and the DLCs were functioning normally before the update.

are there any ideas and solutions?
